I am 66 yrs. old and have terrible dryness of the mouth and get sometimes 20 episodes of dizziness a day. They happen most of the time when I go up any stairs or rise quickly from a sitting or lying down position. It has become very debilitating and keeps me from many normal activities. I normally have a low blood pressure. I always have. That is nothing new. A doctor put me on a steroid (Florinef) to help me retain fluid and it did not seem to work. I drink as much as anyone can in a day.
